BUTTER-WORKER.

SPECIFICATION forming part of Letters Patent No. 417,597, dated December 17, 1889.

Application iiled June 1'7, 1889. Serial No. 314,647. (No model.)

, skilled inthe art to which it appertains to make and 4use thesame.

The invention relates to improvements in machines for working butter when taken from the churn to salt the same and remove the buttermilk therefrom; and it consists in the construction and novel combination of parts hereinafter described, illustrated in the ac- `companying drawings, and pointed out in the claims.

Figure l of the drawings represents a perspective view of a butter-working machine embodying the invention, showing the dog or detent to hold the clutch open. Fig. 2 represents acentral vertical longitudinal section thereof. Fig. 3 represents a rear end view of "themachine, showing the pulley, clutch,and .adjacent parts, the clutch being partially in section to show the spline or feather on the shaft.

Referring to the drawings by letter, A designates the frame of the machine, of general rectangular shape and provided with the up- 4 Vper side rails au, which project rearward beyond the main portion of the frame and have a rise a suitable distance.

bearings on said projecting ends for the 'operating-shaft, hereinafter described.

. o a lare the front legs of the main frame A, and a2 a2 the rear legs thereof. The front legs rise to the upper edges of the correspondingside rails a, while the rearlegsrise a suitable distance above said edges to form the standards a3 a3.

B is the horizontal working-platform of the machine, above which platform the side rails a l The said platform is preferably longer than it is broad, and has at its front and rear ends'the strips'b b', respectively.

The said strips are inclinedl downl ward and inward at angles of about forty-live degrees, and their upper edges are iush with those of the side strips a. T he platform or table B thus forms the floor of a shallowreceptacle X, in which the butter is worked and able points above theV roller-bearings.

y from which thebuttermilk can escape through the aperture b2 in the rear strip b.

b3 is the upper front rail of the main frame connecting the front legs a thereof and lying l against the outer side of the strip b.

Below the platform B a chamber C is formed by the side rails c, connecting the front and rear legs of the main frame just below the rails a, and the bottom c, preferably of sheet metal, secured t'o the lower edges of the rails c at its side edges, at its front edge to the upper edge of the lower front rail c2 of the main frame, and at its rear edge to the lower edge vof the lower rear rail c3, which closes the rear of the chamber C. The said chamber serves to contain ice in summer to keep the butter cool while being worked, its front end being open and the water from the ice escaping through the opening c4 in the rear rail c3.

D is a shaft with its ends journaled in the bearings on the rearward extensions of the side rails o, and having on its ends outside of y said bearings the similar crank-arms cl.

E is a frame composed of two side bars e e, having their rear ends pivoted to the tops of the corresponding standards a3 and the transverse bars e c', to which the rear end of the longitudinal handle e2 is secured. l F F are swinging or vibratory levers having their upper ends pivoted to the front ends of the bars c of the frame E, and thence eX- tending downward, with their lower 'parts lying against the outer surfaces of the sides of the main frame.

G is aroller fitting transversely between the side rails a., its journals. having bearings in the vibratory levers at suitable points. The said journals are provided with suitable washers and transflXing-pins out-side of their bearings to holdthem in place, and the levers F,

by hugging the side rails a and c, act somemeans of these pitmen the rotation of the crank-arms with the shaft Yl) willswing or vibrate the levers F, and will consequently move the roller alternately frontward and rearward over the working-platform.

h is a bar pivoted at its lower end on the front rail b3.- The said bar stands normally IOO vertical and is sufficiently high to catch upon its top the handle c2, thus providing a snpport for the free end of the handle, and also causing the levers F to lift the roller at the forward end of the stroke, so that the same cannot crush the butter against the ends of the strips b and therebybreak the oil-globules. By the said strips being inclined at angles of forty-five degrees the roller in rising near the ends of the working-platform will be prevented from squeezing the butter against their upper edges. By means of the handle c2 the roller can be raised and depressed, and the pressure on the butter thereby regulated.

7L is an arm or bar secured to one of the standards a3 and inclining upward and rearward therefrom. The frame E and roller can be lifted and supported upon the bar 7L when it is necessary to clean the platform or for other purposes.

I is a pulley turning loosely on the shaft D, and with its hub on one side constituting one section yz', of the shouldered clutch J, the opposite section j of which is splined on the said shaft, so that it can move thereon only longitudinally. The pulley is prevented from moving longitudinally by pins which transfix the shaft on each side of it, or by other suitable means. The section j is provided with the usual circumferential groove j for the fork k of the longitudinal operating-rod K, that has bearings in the lower part of the main frame.

The rod K has a rear arm 7c', that rises vertically to its fork, and a front arm It?, that stands horizontally outward, so that by pressing the said front arm downward with his footthe operator turns the rear arm outward and disengages the sections of the clutch. Vhen the front arm is thus depressed, the detent L, which is pivoted at its lower end upon the side of a front leg of the machine, falls slightly forward, and the notch Z in the edge of said detent catches over the front arm and retains the clutch open. The operator can also with his foot move said front arm outward from the notch Z and release it from the detent L. The section j of the clutch is then immediately closed on the section t' by the coiled spring M, that surrounds the shaft D between the outer ends of the section j and a pin transfixing the shaft.

The rod K is preferably made from pipe or tubular for the sake of lightness, and the pulley I may be run by a belt from any proper motor. (Not shown in the drawings.)

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
